IMPROVEMENT IN ARROW-GUNS.

Specification forming part of Letters Patent No. 182,330, dated September 19, 1876; application filed March 13, 1876.

To all whom it may concern:

Be it known that I, CHARLES ROBINSON, of Oambridgeport, in the county ot' Middlesex and State of Massachusetts, haveinvented an Improved Arrow-Gun; and l do hereby declare that the lollowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this speciflcation- Figure l being a side view of the improved arrow-gun and arrow or missile used therewith in place; Fig. 2, a top View of the gun `without the arrow; Fig. 3, a front end view of the same Fig. 4, a top view of the improved arrow or missile, separate.

Like letters designate corresponding parts in all of the figures.

The gun has a stock, A, and breech, B, of ordinary form, there being an arrow-groove, a, in the top of the stock, preferably of semicylin drical form. The arrow or missile O may be of the ordinary form of an arrow, or a simple cylindrical shaft, as shown in the drawings, or of other form convenient for the purpose.

The impelling power to drive the arrow or missile may be a simple elastic cord, D, of the requisite size and strength, inserted through the stock A, near the front end thereof. Instead of reaching back to the rear end of the arrow or missile, to impel theV same, as usual, the elastic cord, when stretched, only reaches back a little beyond the frontend thereof, when in place on the gun, as shown in Fig. l, and catches behind a slightly-raised loop, pin, or other form of projection, b, as represented, on

the side of the arrow, orv by a suitable notch therein.

Thearrow is retained in position until`the discharge thereof takes place `by having a transverse hole, c, orits equivalent, which catches upon a pin, hook, or other projection,

d, in a proper position on the gun near the rear end of the arrow-groove. Thus the cord draws upon the arrow, instead of pushing it, when the arrow is set free. It, therefore, has no tendency to throw the arrow out of its groove, nor to impel it nntruly; but rather to send it exactly in proper line, and to hold thev arrow close down into the groove while irnpelling it. Besides, since the cord is not required to be drawn back nearly so far as usual, less strain is brought upon it, and it therefore retains its elasticity, and it lasts Y impelling-cord arranged to act upon tne arrow I near its forward end, substantially as herein specified.

2. In combination with the foregoing claim, an arrow or missile shaft, O, provided with a means of automatically retaining it in the gun, andwith a means of impelling it forward by a corl, substantially as and for the purpose herein specified.

Specification signed by me this 10th day of February, 1876.
